ROTARY MOTOR.

Specification of Letters Patent.

Patented Mar. 4, 1913.

Application filed July 27. 1911. Serial No. 640,783.

To all whom it may concern .Be it know-n that I. TTAXS 'lxnnorr, engineer. a elt-ixen of the Kingdom of Prussia,

residing at liemiigsenstrhsse 21, Berlin- Schoneberg. (lermany, have invented a cert'ain new and useful Improvement in Rotary Motors, of which the following is a specification.

It is one of the principal disadvantages of comluistion-motors with rota-ting cylinders that it the motor suddenlyreleased \Vltlli out shutting off the supply of fuel 1t Wlll suddenly attain an excessively rapid action, causing such wear and tear of the parts;

that the motor is in danger of bursting.

The present invention is intended to pre in consequenceof thchigh centrifugal strain i The supply of gas being throttlcd by this means the speed of revolution of the rot-ating cylindcr is reduced. the centrifugal 210- tion of the connecting member beingat the same time decreased so thatthe spring presses the connection member down again into the gap, thus actuating the inlet-valve.

The maximum limit of revolution of the rotat ing cylinder canof course be regulated by adjusting the spring to the required pressure. 1

\Vhat I claim is:

In a rotary motor, in combination, a fixed shaft, :1 cylinder rotatably mounted.thereon. an inlet valve for said cyllnder, a cam disk mounted on said shaft and provided vent this abnormally rapid action of the to I lating cylinder and remove the danger of the motor bursting.

with a depressed portion, a-valve rod for actuating said v.alve,"said rod being posi so tinned radially with respect to said shaft- 3 and having its fre end engaging said cam in the accompanying drawings Figure l is a-vertlcal sectional view of the motor. and

Fig. 2is apart view in end elevation.

Referring to the drawings the inlet-valve i connecting member dmvnward into the gap L. The pressure of the spring is coun teracted by the centrifugal action of the connecting member. If this increases with the increasing number of revolutions and finally becomes equal to the pressure of the spring. the latter will no longer be able to hold the connecting member down in the gap and the inlet valve will remain closed.

disk, saidparts being so arranged that when the free end of said rod engages the depressed portion of said disk, said valve will he opened. and when said rod engages the remaining portion of said disk, said .valve will he closed. and a spring normally urging said valve rod into engagement with said cam disk. the tension of said spring being so adjusted that when the speed of the motor attains a predetermined value centrifugal force will counteract the tension of the spring. whereby the valve will be held closed during, the time that the free end of the rod passes over the depressed portion of said disk.

Tn testimony whereof I have hereto afiixed my signature in presence of two witnesses.

HANS WINDHOFF.
